Apelteation filed February 28, 1923. Serial No. 621,719.

This invention is a shingle for roofing and siding purposes, and more particularly,

shingle composed of flexible material.

The material is analogous to' that ordinarily' used in the art, being composed of a basic layer of felt, impregnated or saturated with a waterproofing agent, such as asphaituni, and provided on the Weather surface with two coatings, one of which is com posed of: a relatively high melt point as phaltuin to. resist solar heat and the other consists of granular material incorporated with thesurface coating.

The exposure of material of the foregoing character to solar heat and to the weather tends to distort the uncovered areas and margins of the shingle by curling upwardly the tree unconfined ends oi." the shingles,

' thus displacing said margins relatively to rain and wind.

The object oi this invention is to interlock shingles in a manner'to preclude such distortion of the free ends and margins of the :iiexiblematerial composing the shingles, the

; effect of which is to retain the free ends and n: rgins in a desired close relation to the surface and to exclude rain, snow and Wind "rom entering below the shingles, keeping a ht rooting or siding.

the invention in a practical "form is embodied in a strip shingle provided with a series of so-called tabs protruding from a inaru in of the strip and spaced relatively to each other by the formation in said margin of a series of re-cntra'ut recesses or spaces, the salient "feature of the invention being the provision of an aperture or slot at a definite point in the body of the shingle to the end that the tab of an overlying shingle will be received into said aperture or slot of an underlying shingle.- and thereby lock said tab of an overlying shingle in fixed po sition with respect to the. slot formed part oi the umlerlyinu' shingle, in a manner. to retain flhc free ends and margins exposed to the weather i'rotn distortion and displacement, and to thus exclude wind, rain and edges and ends of the shingles.

llther tum-lions and advantagcs-ot the invention will appear from the following description takcnfn connection"ywtiithe drawings, wherein-- the root surface and permitting the entry of fllach aperture is out out of the body snow front enteringr below such exposed Figure 1 is a'view of a plurality Qf ehinglee in strip form applied in locked relation to each other as embodied in my lllVQlll'lOll.

Figure 2 is a detail plan view of part of a shingle strip embodying the article of my iIWGIltlOIL V, Figure 3 is a cross section on the'line 3-3 of Figure 2.

As shown in the drawings, the invention is embodied, in one practical form, as a continuous strip A, one margin a of which .65 is straight and unbroken, whereas the other margin is of such formation as to produce a succession oi tabs, B, formed by a series of re-cntrant recesses 71, the form and dimensions of which recesses correspond to the shape and sizes. of the tabs of a complemental strip cut in a reversed position from the shingle strip A.

Obviously,-the number of tabs B, and the form and dimensions thereof, on the strip A may be varied as desired, but it is preferred to provide tabs of tapering formation, each having a straight lower'edpie, 0, and side edges 0, inclined to the straight lower edge o. By cutting a complemental strip from the material, and reversing the complemeutal strip to the position of strip A, there results in the strip A a series of recesses lounded by the lines o and c the'ilat or lines 0 being parallel to the longitudinal iifi axis of strip A and parallel also to'edgcs c" at the freeends .0,E tabs l An,,essential feature pt the invention is the provision of apertures Din the sliingle and in a definite relation to the serrated a0 margin thereof, Whith serrated n'iarginis constituted by the presence of tabs B. of the shingle, and in the strip shingle shgiwn, a succession of said apertures is produbed in the body of the shingle strip. Each aperture is represented as a slot, formedin the shingle material. adjacent the boun ary edge and parallel therewith, the len "h of said slot exceeding, the width of the tab at the (rec extremity therooflnnd the width of said slotbeing sufficient for the easy and free insertion thereinto of a tab on the overlying shingle, it being noted that the them one over the other upon a root or against theside of a structure, an-din su'el manner aeto'conceal the straightmargm 1W of the strips, for the .prdtrnding tabs of one strip to he over the recesses in the. ser

rated edge of the underlying strip, the tabs of the overlying and underlying strips lapping at them margins, as shown in Figure 1. In thus assembling the strips the free ends of the tabs B of an overlying strip are bent or deflected slightly and inserted intothe roof the appearance oi hexagonal indi- 1 vi'dual shingles, see Figure 1. Oi viously, the strips are mechanically fastened in a desirable Way, as by nailing them in position, but While the tabs are not thus mechanically fastened, the insertion of the free ends of] said tabs into the slots reduces means by which said otherwise unattached tabs are locked or retained securely with a view to overcoming that tendency of the composite material to curl upwardly under the effects of solar heat and the weather, whereby the tabs are retained in close relation to the surface of a roof or sidingiand thus preclude the entry of rain or snow, as well as'to pre vent the. tabs from being lifted out of position by the pressure of the wind.

My invention is herein shown and described as enibodiedin strip form, and While this is a preferred form, it. is not desired to restrict the invention tostrips for the reason that it may be also embodied in the form of individual or se arate shingles, adapted for assemblage to eteet a desired locking engagement for the free ends-of the overlying shingles with slots in underlyingshingles. Such construction and arrangement may obviously be made by those skilled in the art, and, accordingly it is unnecessary to illustrate or further describe, the same.

Having thus fully described the invention, What I claim as new and desire to secure by Letters Patent" is:

1. Shingles in strip form comprising a body portion having on one margins plus rality of tabs and provided in the body porends of said lapping portions and plurality of slots positioned manor? tion with plyrality of slot-s each oe a definite relation to the inter al two adjacent tabs, the shingles be semblod for the free ends of ovcrlvin to enter the slot in the body 3.1.51.1 ing shingle strip. 2. Strip shingles embodying a body time having on one. margin thereof rahty of tabs and provided on portion with slots extending iengt: the body portion and each slot occ definite relation to the interval two adjacent tabs, the lengtlroit sat mg in excess of the Width oi the '1' free end thereof.

3; Shingles provided with alternat cessed and lapping portions. said s having slots extending; parallel to th outer ends of overlapping shingles retained 1 Within the slots of underlying shinr les.

d Shingles assembled to 'ni'odu e nating recessed and lapping portions,- said slnngles being provided in definite re tion to the recessed portions with slots e tending parallel with the outer ends of? lapping portions, and with said ou r of the overlying shingles inserted slots of underlying shingles.

5. A strip shingle provided on a margin thereo t wlth alternating tabs and recs said shingle having in its lJGtlV port inner termini of said recesses a d said s ots extending in a d rection narallel with outer ends of said tabs.

6. A strip Slilllgl provided on. the gn oithe body portion With alter-n cesses and tabs, the outer ends or" be ng bounded by straight ed shingle having in the. body ,10 ion 1 a succession of slots positioned. adia the recesses, each slot extendi r oi"; "the shingle body and atlas i to the straight end edge portion an 0" mg tab.
